Generally, an IGP indicator means that the route was derived inside the originating AS. EGP generally
means that a route was learned from an external gateway protocol. An INCOMPLETE origin code
generally results from aggregation, redistribution or other indirect ways of installing routes into BGP.
In FTOS, these origin codes appear as shown in
code of INCOMPLETE. The lower case letter (i) indicates an Origin code of IGP.

AS Path
The AS Path is the list of all Autonomous Systems that all the prefixes listed in the update have passed
through. The local AS number is added by the BGP speaker when advertising to a eBGP neighbor.
In FTOS the AS Path is shown in
Path information.
